To all whom t may concern.'

Be it known that I, J orrx F. HILL, a citi-- zen of the United Statesresiding at Griffin, 1n the county of Spalding, State `of. Georgia, have invented a new and useful Rail-Joint and Chair Therefor; and I doi the invention is to )rovide a device of this kind, eliminating the yuse of bolts for clamping through the opposite fish plates of the chair and through the rail. y

Another object of the invention is to provide a. device of this kind, in which o-nly spikes are employed, for fastening the chair and the rails to the tie. I

A further object of the invention is Vto provide an improved, simple and efficient device of this kind, which is practical, and may be manufactured at a small cost.

1n practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

1n the drawings Figure 1 is a plan view of the improved rail joint and chair therefor.

Fig. 2 is a detail perspective view of the chair, showing the opposing fish plates thereof, and illustrating an overhanging flange 011 one side of the chair proper overhanging the side portion of one of the opposing fish plates.

Fig. 3 is a. sectional view on line 3-'3 of Fig. 1. v

Referring more especially to the drawings 1 designates the chair proper of the rail joint, which comprises the base part 2, the overhanging flange 3, which merges integrally into the fish plate 4l, there being an under-cut portion 5, which extends under the flange 3. One side 6 of each of the bases 7 of the adjacent end portions of the rails 8 is received with the under-cut portion 5, as shown clearly in Fig. 3. On the other side of the base 2 is an upstanding flange 9 having an overhanging portion 10 engaging over the lateral base flange 11 of the fish plate 12, which is opposite the fish plate 4, as shown'in Fig. 3. The portion 13 of the base 11 of the fish plate 12 is so shaped, as to fit .over the sideportion 111 of the base 7 of the rail sections, thereby holding the bases 7 of the rail sections securely in position on the base 2 of thechair proper. It is to be noted that the opposing fish plates 4 and 12 are so proportioned as to snugly fit between the o-pposite side portions of the bases of the rail sections and the under portions of the treads 15 of the rail sections,

thereby further insuring security of the rail sections. However, the opposing fish plates Ll and 12 are further so proportioned as to pro-vide spaces 16 between the inner faces of the sh plates l and 12 and the outer faces of the webs of the rail sections, whereby the fish plate 12 may be forced toward the rail sections, so as to force the parts closer together. The side portions 14ev of the bases of the rail sections are provided with notches or recesses 17, which receive the shanks of the spikes 1S which pass through the portion 13 of the base 11 of the fish plate 12, and also through the base 2 of the chair proper, and into the tie 19, thereby holding the parts in their relative positions and securing the same to the tie. The recesses or notches17 are of sufficient size, toL allow expansion and contraction of the rail sec` tion. By means of the spikes 20, the chair proper is secured to the tie, which is secured in position prior to placing the rail sections and the fish plate 12 in position. The base 11 of the fish .-plate 12 is provided with an elongated slot 21, through which the bolt 22 extends. This bolt 22 extends upwardly through the base -2 of the chair, and is provided with a nut 23. A suitable wedge 24 extends between the side edge of the base 11 of the fish plate 12 and the inner face of the flange 9, thereby constituting means for forcing the fish plate 12 toward the opposing fish plate 4, to insure clampingthe rai] sections in place, owing to the fish plate 12, wedging between the base 7 of the rail section and the underportion of the tread 15 of the rail section. Suitable clearance spaces 25 are provided between the side edge portions of the bases 7 of the rail sections and the wall 26 of the under-cut portion 5 and the shoulder 27 of the base 11 of the fish plate 12, so as to permit the fish plate 12 and the rail sections to be forced in position. Y l

The invention having been set forth What is claimed as new and useful is 1. In a rail joint of the kind set forth, the Combination of a rail chair having a base and integral With this base a fish plate which overhangsthe flange of the rail sections and Wedges-between the flange and the tread of said sections, an opposing fish plate separable from the chair but similarly Wedging between the tread and the flange of the rail sections, an undercut fange integral with the base, ay W ed ge acting against this flange to force the fish plate into firm contact with the rail sections, means foi-'securing the chair to a tie, means for securing the separable fish plate 'to the chair and means for securing the Whole to the tie.

2. In a rail joint of the kind set forth, the combination of a rail joint chair having a base and integral with this base a fish plate Copies of this patent may be obtained for which overhangs the fiange of the rail sections and Wedges between the flange and the tread of said sections, an opposing fish plate separable from the chair but similarly Wedging between the tread and the fiange of the rail section, an elongated slot in the bottom of said fish plate, a bolt set in the base and passing through this elongated slot to seeure the fish plate against Vlateral movement when seated, an under-cut flange integral With the base, a ivedgeaeting against this flange to force the fish plate into firm Contact With the rail section, means for securing the chair to a tie and means for securing the separable fish plate, the chair and rails to the tie.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JOHN F. HILL.
